CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit of U.S. Provisional PatentApplication No. 61/305,267 filed on Feb. 17, 2010 and U.S. ProvisionalPatent Application No. 61/419,105 filed on Dec. 2, 2010, the contents ofwhich are incorporated herein by reference in their entirety.

FIELD

The present invention is related to a device for easily andunobtrusively winding, storing, and protecting cords and/or cables.

BACKGROUND

Many devices have a cord or cable associated with the device. Forexample, kitchen appliances such as toasters, coffee makers, andblenders all have a power cable for the transmission of electricalpower. In the digital age, most audio-visual devices have a cord orcable. For example, users use headphones or earbuds with their MP3players and smart phones. Moreover, the cost to replace damaged orbroken cords/cables/headphones is increasingly expensive. Although thereare a variety of winders available to organize and store cords andcables, these conventional devices fail to be user friendly and/or failto adequately wind and store the cord or cable. As such, cablemanagement, including organizing, storing, preventing tangling, andprotecting cords/cables, remains a continued source of frustration formany people. Accordingly, there is a need for devices that organizeand/or make cords easier to use and store.

SUMMARY

It is to be understood that the present invention includes a variety ofdifferent versions or embodiments, and this Summary is not meant to belimiting or all-inclusive.

In accordance with one or more embodiments, winders of various size andcharacteristics are provided to wind and store a variety of cords orcables and to operate “automatically.” As used herein, “automatically”means the winder device in its ready state can operate without turning acrank or handle in order to rotate a winding spool. In use, a foldedportion of a cable or cord is engaged around a grasping member, such asa hook. Thereafter, the cord/cable is pulled slightly to disengage apawl from a spool, and a button is then pushed releasing a spring forwinding the cord/cable around the spool. When the two ends of thecord/cable reach the entry point, the refraction stops. To extract thecord/cable, the user pulls the two portions of the cord/cable, either toa desired length or all the way until the cord/cable releases from thewinder. Alternatively, a locking hook may be used to lock the cable tothe hook so that the cable remains attached to the winder when fullyunwound. As the cord/cable is extracted, the spring is re-loaded for thenext use. Accidental spin-out is prevented by locking the winder devicein its loaded state.

In at least one embodiment, the front interior surface 200 of the backhousing 104 further includes an axle 232 adapted to receive a portion ofthe spool 120. The axle 232 of at least one embodiment is cylindrical inshape and is substantially rigid. Moreover, in at least one embodiment,the axle 232 is formed integral with the back housing 104. However, inother embodiments, the axle may be formed separately from the backhousing and subsequently fastened thereto using a variety of knownfastening mechanisms. The axle 232 may also include a spring anchor 236for securing the drive spring 124 to the axle 232. In at least oneembodiment, the spring anchor 236 is a longitudinal opening that spansthe length of the axle 232 and bifurcates at least a portion of the axle232. In other embodiments, the spring anchor 236 may be a longitudinalgroove (or other receiving portion) that spans at least a portion of thelength of the axle 232. The axle 232 remains fixed (or otherwisenon-rotatable) while under loaded and unloaded conditions. In at leastone embodiment, the axle 232 is made from Acrylonitrile ButadieneStyrene (“ABS”); however, the axle 232 may be made from a variety ofother materials that are durable, low friction, and wear resistant, suchas a metal, or other hard plastic.

In at least one embodiment, the front interior surface 200 of the backhousing 104 further includes a plurality of spokes 240 positionedadjacent to the spool side area 224 and the axle 232. In at least oneembodiment, the plurality of spokes 240 extend radially outward from theaxle 232 toward the spool side area 224. The plurality of spokes 240decrease the surface contact between the drive spring 124 and backhousing 104 and further serve as structural reinforcements for the backhousing 104.

In at least one embodiment, the back surface 204 of the back housing 104includes a surface treatment or material, such as a non-slip, grippable,traction providing, shock absorbing, drop resistant, or other impactresistant material (not shown) to facilitate a user's handling ormanipulation of the winder device 100 and/or to protect the winderdevice 100 from being damaged. Similarly, in still other embodiments,the back surface 204 includes a decorative or aesthetic decal or designto enhance the marketability of the device.

In at least one embodiment, the back housing (including theaforementioned features) 104 are formed integrally. For example, theback housing 104 may be formed using an injection molding or other costeffective manufacturing process or processes.

Referring now to FIGS. 3A-3F, the spool 120 of at least one embodimentof the present inventions is shown. The spool 120 of this embodiment hasa substantially cylindrical configuration, an outer surface 300, a frontsurface 304 a back surface 308, and a plate 312. The plate 312 isgenerally positioned to separate the front surface 304 from the backsurface 308 and\or to prevent the drive spring 124 from interfering withthe pawl 128. In at least one embodiment, the spool 120 has a diameterD.

Referring specifically now to FIGS. 3A-3B, the plate 312 includes anaperture 316 adapted to receive a portion of the axle 232 associatedwith the back housing 104. In one embodiment, the aperture 316 is sizedto have at least some clearance such that the spool 120 may easily slideon and rotate about the axle 232. In other embodiments, ball bearings orother friction reducing materials may be provided at a contact point ofthe aperture 316 and the axle 232.

Referring now to FIGS. 3B and 3F, the back surface 308 of at least oneembodiment of the spool 120 includes a back edge 320 and a hollowportion 324 therein. The back edge 320 includes a first set of holes 328for selectively receiving a plurality of corresponding projections 416positioned on the back spool side 112 (discussed below). Moreover, anynumber of fastening means may be included on the back edge 320 toselectively and/or removably interconnect the back surface 308 of thespool 120 to the first face 400 of the back spool side 112, such asslots or channels.

The hollow portion 324 is adapted to receive the drive spring 124. Thehollow portion 324 substantially encloses the drive spring 124; however,one of skill in the art will appreciate that in other embodiments, thehollow portion 324 may partially enclose the drive spring 124. Thehollow portion 324 helps maintain the shape of the drive spring 124 andalso protects the drive spring 124 from distortion and/or damage.

In addition, in at least one embodiment the back surface 308 of thespool 120 also includes a spring engaging member adapted to engage thedrive spring 124. The spring engaging member of one embodiment is aspring slot 332 that extends from the back edge 320 of the back surface308 longitudinally along the outer surface 300 to some length or depth.The length of the spring slot 332 may vary depending on the type or sizeof the drive spring 124 that is used for a particular winder.

Referring now to FIGS. 3A and 3E, in at least one embodiment, the frontsurface 304 includes a front edge 336 that has a second set of holes 340and teeth 344. The second set of holes 340 are adapted to receive aplurality of projections 416 positioned on the front spool side 116(discussed below). Any number of interconnecting mechanisms, such asslots or channels, may be included on the front edge 336 to selectivelyand removably interconnect the front surface 304 of the spool 120 to thefirst face 400 of the front spool side 116.

The teeth 344 generally project radially inward (i.e., toward the centerof the spool 120) and are sized and shaped to engage at least a portionof the pawl 128. The teeth 344 are oriented at an angle α in order toreduce and/or prevent winder spin-out. Accidental spin-out isundesirable because a user has to then manually re-load the drive spring124 before the cord/cable may be wound. As such, the engagement betweenthe spool 120 and the pawl 128 is configured such that the drive spring124 is maintained in a loaded condition until the user is ready to windthe cord/cable (thereby unloading the drive spring). In order to achievethe desirable spool/pawl engagement, the teeth 344 are properly angledto engage and maintain the engagement (i.e., minimize slip) with thepawl teeth 616. In at least one embodiment, this engagement is achievedby orienting the teeth 344 at an angle α that ranges from about 25degrees to about 45 degrees. In a preferred embodiment, the teeth 344are oriented at an angle α of about 37 degrees.

Referring back to FIGS. 3A-3F, the outer surface 300 of the spool 120includes a plurality of grasping members. In at least one embodiment,the grasping members are hooks 348 adapted to selectively engage aportion of a cord, cable, or other object to be wound with the windingdevice 100. The number of hooks 348 positioned on the outer surface 300of the spool 120 may vary depending on a number of variables, such assize and the graspability of the object. Moreover, the grasping membersare not limited to hooks and may include a variety of configurations,geometries, and superficial features that are adapted to assist withgrasping and/or selectively retaining the cord/cable. Consequently, theheight H of the spool 120 may vary depending on the exact configurationof the grasping members. In some embodiments, it may be desirable toinclude locking hooks to lock the cord/cable to the hook so that thecord/cable remains attached to the winder device when fully unwound.

In at least one embodiment, the spool 120 is manufactured as an integralpiece using any number of conventional manufacturing processes, such asinjection molding, and is made at least partially from Delrin, or othersimilar materials. In other embodiments, the grasping members may beindividually and/or selectively interconnected to the outer surface 300of the spool 120, depending on the application.

Referring now to FIGS. 4A-4E, a spool side of one embodiment is shown.In at least one embodiment, the winder device includes two spool sides,adapted for positioning on either side of the spool. In otherembodiments, the winder device has no spool sides. In yet otherembodiments, the winder device has only one spool side. In still yetother embodiments, the spool sides are formed integrally with the spool.

In at least one embodiment, the winder device 100 includes a back spoolside 112 and a front spool side 116. The back and front spool sides 112and 116 may be substantially identical parts. As such, the spool sideshown in FIGS. 4A-4E, can be either the back spool side 112 or the frontspool side 116. Because the back and front spool sides 112 and 116 aresubstantially identical, the number of different component parts thatneed to be manufactured decreases and the throughput of the manufacturedparts increases. However, in some embodiments, it may be desirable tohave back and front spool sides 112 and 116 that are not substantiallyidentical parts. For example, the back and front spool sides 112 and 116may have different interconnecting mechanisms that allow the spool 120to be selectively removable from the back and front spool sides 112 and116.

In at least one embodiment, the back and front spool sides 112 and 116are adapted to interconnect with the spool 120. The back and front spoolsides 112 and 116 have a first face 400, a second face 404, an outerdiameter 408, an inner diameter 412, and a substantially planar torusshape. The first face 400 of back spool side 112 is adapted tointerconnect to the back surface 308 of the spool 120 and the secondface 408 of the back spool side 112 is adapted to abut the spool sidearea 224 of the back housing 104. Similarly, the first face 400 of thefront spool side 116 is adapted to interconnect to the front surface 304of the spool 120 and the second face 404 of the front spool side 116 isadapted to abut the spool side area 732 of the front housing 108.

In addition, in at least one embodiment, a plurality of projections 416positioned on the first face 400 of the back and front spool sides 112and 116 are positioned proximate to the inner diameter 412. Theplurality of projections 416 may be spaced, equidistantly,non-equidistantly, or in any number of other configurations, around theperimeter of the inner diameter 412. In at least one embodiment, theplurality of projections 416 have a dowel pin or cylindrical rod shape.The plurality of projections 416 are adapted to be received bycorresponding fastening means, i.e., in corresponding holes on the frontand back surfaces 304 and 308 of the spool 120. Moreover, the pluralityof projections 416 may have various shapes and/or geometry, so long asthe spool 120 has corresponding or mating interconnection means.

The back and front spool sides 112 and 116 may be made from any numberof materials, including thermoplastics, such as Delrin having highstiffness, low friction, and good dimensional stability. Moreover, thespool sides 112 and 116 may be manufactured using a number of methodsand/or processes, including injection molding.

An exemplary biased member isillustrated in FIGS. 10A-10C. In at least one embodiment, the biasedmember is a coil or helical button spring 1000. The button spring 1000may be made from a number of materials. The button spring 1000 isadapted for positioning within the spring receiver 916. As such, theclip 740 is proximate the button spring 1000. The button spring 1000 ofat least one embodiment is adapted to store and release a sufficientamount of energy such that when the button 132 is moved from a firstposition of use to a second position of use, the button spring 1000 isloaded (i.e., compressed against the clip 740) and when the button 132is moved from the second position of use to the first position of use,the button spring 1000 is unloaded (i.e., expands away from the clip740).

The front face 900 of the button 132 may include surface features toassist a user's manipulation of the button 132. For example, in at leastone embodiment, the front face 900 has a grippable or textured surface(not shown) such that users of varying age and dexterity may slidablymove the button 132.

Although an exemplary winder device 100 is depicted in FIGS. 1A-10C, oneof skill in the art can appreciate the winder device 100 may be sized upor down depending on the application and the type of cord/cable used.For example, for extension cords, power cords or otherlarger/longer/thicker cords, the winder device may require a large sizewhereas, for kitchen appliances and computers, the winder device mayrequire a medium size, and whereas, for headphone and cellular phones,the winder device may require a small size. That is, the size of thewinder device may be designed large enough to store and protect the typeof cable/cord while also small enough to be non-bulky and unobtrusive.

Referring now to FIGS. 11A-11C, the operation of at least one embodimentof the winder device 100 is shown. FIGS. 11A and 11B show that as a userpulls the cord/cable 100 associated with the winder out of (or at leastpartially out of) the winder device 100, the spool 120 rotates. When thespool 120 rotates, the spool 120 engages the pawl 128 and torque istransmitted to the drive spring 124. As such, the rotation of the spool120 causes the drive spring 124 to wind/spiral tighter, which loads thedrive spring 124. In the loaded condition, the drive spring 124 stores acertain amount of energy. Moreover, as the spool 120 rotates, the teeth344 on the spool 120 selectively engage the pawl teeth 616 such thatwhen the user stops pulling on the cord/cable 1100, the pawl teeth 616lock the position of the spool 120 in place. Because of the engagementbetween the pawl teeth 616 and spool's teeth 344, the spool 120 is heldin place and is maintained in a loaded state, which prevents the drivespring 124 from releasing its energy.

FIG. 11C shows how the cable/cord 1100 is wound into the winder device100. When the user is ready to wind the cable/cord 1100 onto the spool120, the user loops the cable/cord 1100 around one of the graspingmembers (hooks in the embodiment shown) and pulls slightly to exert someforce against the cable/cord 1100 to at least partially disengage thepawl teeth 616 from the spool 120. Once the pawl teeth 616 havedisengaged, the user is able to move the button 132 from a firstposition of use to a second position of use (by moving the button up inthe embodiment shown), which moves the pawl teeth 616 away from thespool's teeth 344. Once the pawl 128 and the spool 120 are disengaged,the drive spring 124 is able to release and return to an unloaded state.Unloading the drive spring 124 causes the spool 120 to spin and wind thecable/cord 1100 into the winder device 100. One of skill in the art willappreciate that having both ends of the cord/cable at one entry point(rather than each end of the cord/cable coming out of different entrypoints) is desirable in that both ends of the cord can be quicklyaccessed.

It is desirable to be able to keep the drive spring in a loaded state sothat the spool is ready to wind the cable/cord when the user is ready.As such, it is desirable to prevent accidental spin-out (or unloading)of the drive spring. In at least one embodiment, accidental spin-out isprevented by preventing the button from moving when a cord/cable is notengaged with the winder device. That is, the button cannot move from afirst position of use to a second position of use unless and until acord is engaged with the spool and the user pulls slightly on the cordwhile moving the button. A user who completely removes his or herheadphones from the winder device is prevented from accidentallyunloading the drive spring because he or she may not move the button toa second position of use until the cord/cable has been re-engaged withthe spool's grasping members and the user has pulled slightly on thecord/cable. Similarly, a user who partially removes his or her earbudsfrom the winder device is prevented from accidentally unloading thedrive spring because he or she has to pull slightly on the cord/cablebefore he or she may move the button to a second position of use.Preventing accidental spin-out is highly desirable for the user who, forexample, takes his or her earphones out of the winder device and thenplaces the winder device in a backpack, briefcase, or purse while he orshe is using the earphones. In this example, the winder device will notaccidentally unload while in the backpack, briefcase, or purse and thewinder device is ready to wind the cord/cable when the user is ready to.If, however, the drive spring does spin-out or unload accidentally, theuser may simply reload the drive spring by manually rotating the spool.

Referring now to FIGS. 12-23, another embodiment of the presentinventions is illustrated. To draw a few exemplary and non-limitingdistinctions between the winder device 100 of at least one embodiment(discussed above) and the winder device 1200 of at least anotherembodiment (discussed below), one will notice that in the embodimentshown in FIGS. 12-23, the winder device 1200 includes front and backcover plates. One of skill in the art will appreciate that depending onthe application or use of the winder, it may be desirable to have or nothave front and back cover plates. For example, when a lower profilewinder is desirable, the winder device 100 without cover plates may beadvantageous. Alternatively, when a more robust winder is desired, thewinder device 1200 having cover plates may be advantageous. To furthercontrast the at least two embodiments, the winder device 100 has an axle232 that is integral to the back housing 104 whereas the winder device1200 has an axle 1220 separate from the back cover plate 1204 and backhousing 1212. Again, depending on the particular application or use ofthe winder device, it may be desirable for the winder device to havefewer individual components such that the efficiency of themanufacturing and/or assembly processes are increased. In contrast, itmay be desirable to have a separate axle if the cable/cord to be woundrequires a stronger axle.

For example, in at least one embodiment, four hooks areprovided. In another embodiment, two hooks are provided. In yet anotherembodiment, seven hooks are provided. One of skill in the art willappreciate that the grasping members may include a variety ofconfigurations. The grasping element may take on a variety of differentforms and is not limited to a hook. By way of example and notlimitation, a V-shaped engaging mechanism that uses friction to hold thecord/cable and allows the winder to pull the cord/cable into its framemay be used. In at least another embodiment, a cord engaging mechanismincludes texturing for a plurality of superficial features to assistwith grabbing and holding the cord/cable. The height H of the spool 1232may vary depending on the exact configuration of the grasping members.

In at least one embodiment, the spool 1232 is manufactured as anintegral piece using conventional injection molding processes and ismade from polyoxymethylene plastic (commonly sold under the trade name“Delrin”). In other embodiments, the grasping members may beindividually and selectively interconnected to the outer surface 1600 ofthe spool 1232, depending on the application. In another embodiment, theteeth 1644 may be selectively removable from the front surface 1604 suchthat they may be easily replaced if they get worn or otherwise damaged.

The plurality of projections 1716 are adapted tobe received by corresponding fastening means, i.e., in correspondingholes on the front and back surfaces 1604 and 1608 of the spool 1232.One of skill in the art will appreciate that the plurality ofprojections 1716 may have various shapes and/or geometry, so long as thespool 1232 has corresponding or mating fastening means. One of skill inthe art will appreciate that any number of fastening mechanisms,including screws, rivets, retaining rings, snap fits, or glues and otheradhesives, can be used to interconnect the front and back spool sides1228 and 1224 to the spool 1232.

In at least one embodiment, the front and back spool sides 1228 and 1224are substantially identical parts. One of skill in the art willappreciate that using front and back spool sides 1228 and 1224 that aresubstantially identical decreases the number of different componentparts that need to be manufactured and increases the throughput ofmanufactured parts. However, one of skill in the art can also appreciatethat in some embodiments, it may be desirable to have front and backspool sides that are not substantially identical parts. For example, inother embodiments, the front and back spool sides 1228 and 1224 havedifferent fastening mechanisms, are made from different materials, orhave different dimensions. In another embodiment, the front and backspool sides 1228 and 1224 are integrally formed with the spool. In stillother embodiments, the winder device only includes one spool side.
